I'm looking at a Twin Bonanza Excalibur equipped with GSIO-540s. I'd love to hear from those who have actually flown behind these engines for comments on actually reliability, durability, operating proceedures, and the ability to run lean of peak.

The best thing about these airplanes is they have great systems. My guess is that one of the hydraulic pumps failed in the recent past when a leak occured. The other one failed after a 3.5 hour flight from Arkansas to Hooks airport... A small crack occured at the firewall hardline fitting, and started leaking sometime into the flight... By the time the guys noticed something was wrong, they were about 100 miles out, and the gear was coming down on its own. Pressure was fluctuating from 500 to 700 (accumulator pressure only) which will not allow for gear retraction... Anyways, to make a long story short... The airplane (500-A colemill conversion) has PESCO pumps p/n 1P349L, which came on the plane. PESCO is out of business... Just wondered if anyone out there has a used servicable or yellow tagged pump in stock you want to sell... OR is there a replacement manufactured pump available, and what is it ??? Just throwing this out to all the folks out there who are in the know... THANKS AS ALWAYS!!!!!
